The amount of heat obtained by the complete combustion of 1 kg of a fuel when the products of its combustion are cooled down to the temperature of supplied air is called __________ calorific value offuel.

The polytropic index (n) is given by

Kerosene is distilled at

The heat and work are mutually convertible. This statement is called __________ law of thermodynamics.

Relation between c_p and c_v is given by (where c_p = Specific heat at constant pressure, c_v = Specific heat at constant volume, γ = c_p/c_v, known as adiabatic index, and R = Gas constant)
